🔑 Hash Generator

This tool generates cryptographic hash digests from your text input using the Web Crypto API.

• SHA-1: 160-bit hash (40 hex chars) — legacy, avoid for security-critical use.
• SHA-256: 256-bit hash (64 hex chars) — the most widely used secure hash.
• SHA-384: 384-bit hash (96 hex chars) — extended security variant.
• SHA-512: 512-bit hash (128 hex chars) — maximum security hash.

All hashing is done client-side using your browser's built-in crypto.subtle API. No data is ever sent to a server.
